Synanceia horrida, commonly known as the Stonefish, is one of the most venomous fish species found in marine aquariums. Native to the Indo-Pacific region, this scorpionfish is renowned for its exceptional camouflage and potent venom, making it a fascinating yet challenging addition to a marine tank.
Care Level: Advanced. Due to its venomous spines and specialised husbandry needs, Synanceia horrida is recommended only for experienced aquarists.
Temperament and Compatibility: This species is generally sedentary and solitary. It can be kept with other robust fish species but should not be housed with small or slow-moving fish that may be mistaken for prey. Exercise caution when handling or maintaining the tank.
Diet: Carnivorous. Synanceia horrida primarily feeds on live or frozen meaty foods such as crustaceans and small fish. Feeding should be done carefully to avoid stress and ensure proper nutrition.
Tank Requirements: A minimum tank size of 180 litres (approximately 50 gallons) is recommended to provide ample space and stable water conditions. The tank should have plenty of live rock for hiding and camouflage, with a sandy or rubble substrate.
Water Parameters: Maintain stable marine conditions with temperature between 24-27°C, salinity at 1.023-1.025 SG, pH 8.1-8.4, and moderate water flow.
Reef Safety: No. Synanceia horrida is not reef safe and may prey on small invertebrates and fish.
Handling Precautions: Due to its venomous spines, always use extreme caution when performing tank maintenance or moving the fish. Protective equipment and specialised tools are advised.
Overall, Synanceia horrida is a striking and unique species that adds intrigue to a marine collection but demands respect and careful husbandry.
